Test photo: 3EV over 12,800. Photographed at dusk in the shadows. Extreme cropped (90% pixels lost). Many critics think of the 102K ISO as a gimmick but let's say these birds were thought to be extinct. Would you want a photograph of them (albeit grainy) or nothing at all? FYI: DxO Optics Pro 7.5 does a very nice job of reducing digital noise.
